What to choose: Node.js vs Java?

What to choose: Node.js vs Java?
  • PublishedDecember 15, 2022

Many developers wonder how Java differs from Node.js. This is a question that baffles so many. Therefore, to understand the main features of these two tools, continue reading this article.

There is such a variety of languages ​​in the world of programming that it is important to distinguish when it is appropriate to use one and when the other. Java is the king of programming due to its age and development in the market. Java is the #1 language for DevOps, AI, VR, Big Data, Continuous Integration, Analytics, Mobile,

Chatbots, and Social. But new frameworks like Node.js are taking the lead among high-tech companies as a way to make things easier, as well as a fast option for high-traffic web applications.

Why should you choose Java?

It is the most complete programming language that most developers on the market work with. It has served many businesses and provided them with controllers, debuggers, and other tools that integrate the language to cover all the steps of a task that a programmer performs. Its age is synonymous with solidity, although the complexity of its resources affects its functions: it becomes increasingly difficult to learn how to implement it.

Working with databases requires the memorization of different languages ​​to be able to process them. They are executed with threads, understood as parallel and independent sequences, which execute thousands of threads while executing a task. Threads can share a memory, so changes to one of them do not mean loss of information or work. However, the downside of shared memory is that the application can become inconsistent when threads change since multiple processes need to be coordinated at the same time.

Why should you choose Node.js?

While it takes several years to fully master Java, and the tools it includes are constantly updated and require constant learning, Node.js is perfect for beginners who want to approach programming with an easy-to-use language. If you are already working with JavaScript, which is present in some elements of almost all websites, the learning process will be fast. This is especially useful for dynamic websites that support high volumes of real-time traffic, becoming the language of the future for future applications.

Compared to Java, its resources are less developed due to the obvious difference in the time of their introduction to the market. However, it always uses the same syntax – the way the code is written – whether it’s a client or a server. Usually, one syntax is required for the client and another for the server, but Node.js solves the problem by avoiding double tasking in the scheduler with data being exchanged between both at the same time.

When should you learn Java and when should you learn Node.js?

Both are viable in engineering fields, although each has idiosyncrasies that make it more suitable for a given situation. Java is more suitable if you are building a system in real-time because it is faster, but be aware that the range of its capabilities comes with difficulties in internalizing its work. It is static, so it is less applicable to dynamic networks, and the complexity of its syntax requires many hours of study.

On the other hand, Node.js solves synchronization problems much faster because it works without threads, that is, it does not use threads to complete a task, but directly addresses one line of work. Ideal for beginners, dynamic websites for technology or communications companies, or those that need to support thousands of users browsing at once.
